目的：探讨以眩晕为主诉患者的常见病因及分布特征。方法：入选200例以眩晕为主诉的患者，根据临床症状体征、Dix-Hallpike试验及头颅CT/MR、TCD等检查结果并分析病因。结果：在200例患者中良性发作性位置性眩晕86例（43%），后循环缺血（PCI）65例（32.5%），其中椎基底动脉系统TIA27例（13.5%），脑干梗死22例（11%），小脑梗死16例（8%），神经症22例（11%），梅尼埃病15例（7.5%），前庭神经元炎8例（4%），小脑出血3例（1.5%），病因不明确3例（1.5%）。结论：BPPV是眩晕最常见病因。患者发病年龄和持续时间可以作为眩晕鉴别诊断的参考指征。%Objective To discuss the causes of diseases presenting vertigo as a chief complaint in patients in department of neurolo-gy. Method 200 patients with a chief complaint of vertigo were followed up in the department of neurology. Physical examinations with spe-cial attention to neurologic systems and Dix-Hallpike maneuver were performed. Based on the history,the physical examination,Dix -Hallpike maneuver and special techniques,the diagnoses of 200 patients with vertigo was made. then obtained the thorough history,especial-ly the timing and duration of vertigo. Results The main diagnoses for these patients were BPPV( 43%),PCI( 32. 5%),neurosis( 11%), Meniere′s disease(7. 5%),vestibularneuronitis(4%),cerebellar hemorrhage(1. 5%),Such clinical features of the diseases with vertigo, as age,vertigo duration,and provoking fators,associated sympotoms,risk factors,the physical examinations,the treatment and so on were summed up. Conclusion Presentations of vertigo can be clinically diagnosed in most cases,with a larger number of patients suffering from BPPV. Age and duration of vertigo were important for diagnosis of vertigo.
